Abstract
To address the urgent demand for sustainable battery manufacturing, this review contrasts traditional wet process with emerging dry electrode technologies. Dry process stands out because of its reduced energy and environmental footprint, offering considerable economic benefits and facilitating the production of high-energy-density electrodes. We spotlight technological innovations that exemplify the paradigm shift towards eco-friendliness and cost-efficiency. This review synthesizes the latest developments in dry electrode production, comparing the techniques with conventional methods, and outlines future research for further optimization toward a higher technology readiness level. We suggest that the evolution of battery manufacturing hinges on the synergy between process innovation and materials science, which is crucial for meeting the dual goals of environmental sustainability and economic practicality. Developing a process for dry electrode fabrication is required to achieve high-energy-density batteries and carbon neutralization through thick electrode construction and organic solvent removal, respectively. This review highlights promising concepts focused on manufacturing processes and binder materials of dry electrode to substitute slurry-based electrode. image
